Aluminum Laminated Fiberglass Sleeving is an advanced, high-performance tubular sleeving engineered for superior protection in demanding thermal and mechanical environments. It represents a synergistic fusion of two critical materials: a robust fiberglass substrate permanently bonded to a highly reflective aluminum foil outer layer. This composite construction creates a versatile, single-piece solution designed to shield sensitive components from radiant heat, physical abrasion, and chemical exposure.

Advanced Construction and Key Features

The efficacy of this sleeving lies in its sophisticated, virtually seamless manufacturing process. By laminating the aluminum foil directly onto the fiberglass base, it eliminates fraying edges and creates a low-profile, durable jacket that is both flexible and easy to install.

• Radiant Heat Reflection: The primary function of the outer aluminum layer is to act as a highly effective thermal mirror. It reflects up to 90% of radiant heat away from the components it encloses, such as hoses, tubing, and wiring harnesses. This reflective capability allows it to operate continuously in temperatures up to +500°F (+260°C), preserving the integrity and functionality of the protected parts.

• Dual-Layer Mechanical & Chemical Armor: Beyond thermal management, the sleeving provides a formidable barrier against physical and chemical threats. The aluminum foil layer offers excellent resistance to fluids, oils, fuels, and many chemicals, while also protecting against abrasion, scraping, and cuts. The underlying fiberglass adds significant tensile strength and an additional layer of thermal insulation, creating a comprehensive defensive system.

• EMI/RFI Shielding Properties: The continuous aluminum surface provides a degree of shielding against Electromagnetic and Radio Frequency Interference (EMI/RFI). This helps prevent signal degradation in sensitive control cables and wiring, making it suitable for automotive, aerospace, and industrial automation applications.

• Uncompromised Flexibility and Ease of Use: Despite its robust construction, the sleeving remains remarkably flexible, allowing it to be routed around tight bends and complex geometries without kinking or cracking. It can be effortlessly cut to length with ordinary scissors, facilitating quick, custom-fit installations and on-the-spot repairs, which reduces labor time and cost.

Typical Applications

This sleeving is indispensable across industries where heat management and component longevity are critical. Common applications include:

• Automotive & Aerospace: Protecting fuel lines, hydraulic hoses, A/C lines, and engine bay wire harnesses from exhaust manifold heat.

• Hybrid & Electric Vehicles: Shielding high-voltage cables and battery cooling lines.

• Industrial Machinery: Insulating hydraulic and pneumatic tubing, control cables, and wiring in high-temperature manufacturing environments.

• Marine Applications: Shielding components in engine rooms from heat and fluid exposure.

Summary of Advantages

• Reflects radiant heat up to 500°F (260°C)

• Excellent abrasion, cut, and fluid resistance

• Provides secondary EMI/RFI shielding

• Flexible, seamless, and non-fraying construction

• Easy to cut and install for a custom fit

• Durable, low-profile design for confined spaces

In essence, Aluminum Laminated Fiberglass Sleeving is more than just a protective cover; it is an integrated thermal management and preservation system, engineered to extend service life and ensure reliability for critical components operating under extreme conditions.
